You must supplement if you are feeding a homecooked diet. The proper calcium to phosphorus ratio is very important. At the very least dogs on a homecooked diet need a high quality multivitamin and a Tums everyday. |

Over supplementing when using commercial food isn't a good idea.
It is not an option when you homecook and just a multi-vitamin does not provide enough calcium and the cal/phos ratio is not balanced. So many vitamins and minerals are already added to dog food that you don't need to add anymore.
